LOUIS WILPUTTE, OF NEW ROCHELLE, NEW YORK, ASSIGNOR OF TWO-THIRDS TO I ALICE A. WILPUTTE, OF NEW ROCHELLE, NEW YORK.

COKE-OVEN-DOOR MECHANISM,

To all whom it may concern:

Be it known that I, LOUIS WILPUTTE, a citizen of the United States, and resident of New Rochelle, in the county of \Vestchester and State of New York, have invented certain new and useful Coke-Oven-Door Mechanism, of which the following is a specification.

The general object of my present invention is to provide improved means for opening and closing the ends of horizontal coking chambers. More specifically, the object of my invention is to provide a horizontal by-product coke oven having an oven door and doorway construction permitting the door to have a substantial upward movement out of its closed position, with a novel door handling mechanism, proper, characterized by itssimplicity and reliability of construction and operation.

The various features of novelty which characterize my invention are pointed out with particularity in. the claims annexed to, and forming a part of this specification.

For a better understanding of the invention, however, and the advantages possessed by it, reference should be had to the accompanying drawings and descriptive matter, in which I have illustrated and described a preferred embodiment of my invention.

Of the drawings:

Figure 1 is an elevation of the door handling mechanism, and'also shows a portion of the coke oven structure in section on a. plane passing centrally through one of the oven chambers.

Fig. 2 is an elevation at right angles to Fig. 1, showing the door handling mechamsm proper.

Fig. 3 is a partial plan in section on the line 3-3 of Fig. 2; and

Fig. 4 is a partial plan in section on the line 44 of Fig. 1.

The horizontal coke oven structure shown is of the ty e illustrated in my copending application, erial No. 228089, filed April 12, 1918; in that a door receiving groove A is formed in one side wall or face of the oven structure A above the corresponding end of each coking chamber A Each door B has its upper end received in the corresponding groove A while the lower portion of the door projects into the corresponding oven chamber (see Fig. 4) as does the ordinary plug door now in general use in by-product Specification of Letters Patent.

Serial No. 258,332.

, of the door. A tight jointis obtained by applying luting clayalong the surface B at the bottom and sides of the door, and along the surface 13 at the top of the door. Each door B is provided at its upper 'end with an eye B for engagement by the door handling mechanism proper. The described door and oven arrangement permits the door to have a substantial vertical movement upward out of its closed position while still between the side walls of the oven chamber. In its closed position the shoulders B of each door are held snugly against the corresponding flash plates C by means of a bar 13 secured to the door andengaging inclined guides C secured to the adjacent buckstays CA.

The door handling mechanism is mounted on a carriage D having wheels D running on track rails E carried by the coke bench or platform A. As shown, this carriage is also provided with a coke guide D through which the coke mass discharged from an oven chamber is pushed on to the usual coke quenching car or other coke receiving device. F reBresents the motor for moving the carriage along the rails E. The 'door handling mechanism proper comprises a lever arm G which is pivotally connected through a shaft G to the framework of the carriage D at a level approximately that of the tops of the doors to be manipulated when the latter are in their closed positions. The lever arm G is provided at its free end with a hook H pivotally connected at G to the lever G and adapted to engage the eye B of a door to be moved into and out of place. The "lever arm G. also has pivotally connected to it, adjacent its free end, a pulley G A cable or other flexible element I running over the pulley G has one end fixed B of each door operated upon, I advantageously provide the hook H with an operating arm H which is connected by a link K to a rock shaft K mounted on the carriage l), and having an arm from whlch an operating handle K is suspended. The shaft K is located at about the same level as the shaft G and the parts are preferably so proportioned that as the arm G is turned about the axis of the shaft G the hgok H may maintain its vertical position without causing the shaft K to rotate appreciably. By means of a counterweight K secured to an arm carried by the rock shaft K and tending to rotate the latter in the direction to swing the hook H toward the door, and an adjustable stop K limitin this movement of the rock shaft 1%, the hook H may be caused to automatically engage the eye 13 of a door to be opened, when the arm G is lowered into the door engaging position. The handle K forms a means for disengaging the hookH from the door eye B after the door has been returned to its closed position.

In operation, after the carriage D is brought into the proper position 1n front of the door tobe opened, the hoist J is operin full lines in Fig. 2. Since thefulcrum axis of the lever G is at approximately the level of the top of the door B, the initial opening movement of the door is mainly vertically upward, but as the opening movement continues, the door is carried outward to clear by a sufficiently wide margin, the oven buckstays CA. To prevent undesirable swaying of the door when in the position shown in dotted lines in Fig. 1, 1 advantageously provide the carriage D with guides D between which the door 1s received when in its elevated position.

When it is desired to put the door back into its closed position, it is necessary only to make sure that the carriage D is in the proper position in front of the coking chamber, and then to operate the drum J to permit the door to move back into its seat under the action of gravity. As the door moves back into its seat, the ends of the bar B engage the corresponding lugs G carried by the buckstays CA, and thus wedge the door into place with the shoulders B in snug engagement with the corresponding portions of the flash plates C. Preparatory to closing the door, a layer of lilting clay may be placed at the bottom of the door-. way in position to be engaged by the bottom portion. of the door luting surface turning when the door returns to its closed position. Preferably the eye B is above the center of gravity of the door so that the latter tends to remain plumb when suspended from the hook H.

As those skilled in the art will well understand, practical consideration frequently makes it desirable to employ different types of doors and door handling machines at the opposite ends of the coking chambers, and while the present invention may be used at either side of the oven structure, I consider it especially desirable for use, as shown, at the coke side of the battery. While with my improved form of door handling mechanism the initial opening movement of the door is a substantially ver- .tical movement of considerable magnitude,

the door is not entirely removed from the oven chamber shown by this vertical movement, and the groove A above each oven chamber A need not be shaped as shown in my previously mentioned application so as to permit the door to be elevated for its full length through this groove. It is apparent, however, that the improved door handling mechanism shown herein can well be used with an oven structure formed exactly as shown in my said prior application, as well as with still different types of door and doorway constructions.

While in accordance with the provisions of the statutes, I have illustrated and described the best form of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed with out departing from the spirit of my invention as set forth in the appended claims, andthat certain features of my invention may sometimes be used with advantage without a corresponding use of other features.

Having .now described my invention, what I claim as new and desire to secure by Letters Patent, is:
